    • There is provided a magnetic recording apparatus capable of carrying out signal reproduction with high accuracy by using a narrow gap head structure corresponding to high recording density. An asymmetric gap structure MR head includes a magnetoresistance element 26 having a magnetoresistance film 24 and a pair of electrodes 25 disposed at the upper side; a reproducing magnetic gap film 23 disposed only at the lower side of the magnetoresistance element 26; a magnetic shielding film 22 disposed so as to make a laminate with the magnetoresistance element 26 through the reproducing magnetic gap film 23; and an insulating film 27 disposed at the upper side of the magnetoresistance element 26. When a signal is read by use of such a reproducing head, the signal of the present bit is read by subtracting a value obtained by multiplying signals of a plurality of previous bits by predetermined coefficients from the present reproduction signal. As another reproduction signal processing system, a partial response system is adopted.
    • 提供了一种能够通过使用对应于高记录密度的窄间隙头结构以高精度执行信号再现的磁记录装置。 非对称间隙结构MR头包括具有磁阻膜24和设置在上侧的一对电极25的磁阻元件26。 设置在磁阻元件26的下侧的再现磁隙膜23; 设置成通过再现磁隙膜23与磁阻元件26层叠的磁屏蔽膜22; 以及设置在磁阻元件26的上侧的绝缘膜27.当通过使用这种再现头读取信号时,通过减去通过将多个先前的信号乘以信号而获得的值来读取当前位的信号 比特由来自当前再现信号的预定系数。 作为另一再现信号处理系统,采用部分响应系统。

    • An opening for discharging toner is formed in a lower part of a cartridge body containing toner. A shutter mounting body is mounted on the opening. A first shutter is slidably mounted on the shutter mounting body. A second shutter is slidably mounted on the first shutter. A front end of a sealing member for sealing the opening is extended, the extended front end being inserted through a seal traction opening formed in a front end of the second shutter, and fixed to a front end of the first shutter. When the second shutter is pulled out of the shutter mounting body, the sealing member is towed by the seal traction opening. In addition, the first shutter is further towed by the sealing member, to be also pulled out. Consequently, nearly half of the sealing member from its front end is stripped. When the second shutter is further pulled out after the movement of the first shutter is regulated, the seal traction opening in the second shutter tows the sealing member while allowing the insertion of the sealing member. At this time, the sealing member is stripped while being so folded that a toner adhering surface is located in its inside. In this construction, the stroke for stripping is decreased, thereby to make it possible to prevent contamination by toner as well as prevent a large part of the sealing member from being ineffective.
    • 在含有调色剂的盒体的下部形成有用于排出调色剂的开口。 快门安装体安装在开口上。 第一挡板可滑动地安装在挡板安装体上。 第二挡板可滑动地安装在第一挡板上。 用于密封开口的密封构件的前端延伸,延伸的前端通过形成在第二闸门的前端的密封件牵引开口插入并固定到第一挡板的前端。 当第二挡板从快门安装体拉出时,密封构件被密封件牵引开口牵引。 此外,第一挡板被密封构件进一步牵引,也被拉出。 因此,从其前端的密封件的近一半被剥离。 当第一挡板的移动被调节后第二挡板进一步拉出时,第二挡板上的密封件牵引开口在允许密封构件的插入的同时牵引密封构件。 此时,密封构件被折叠,同时使调色剂粘附表面位于其内部。 在这种结构中,用于剥离的冲程减少,从而可以防止调色剂的污染以及防止大部分密封件无效。
